How to calculate the rate of Wi-Fi 6? First, guess from the beginning to the end:  The transmission rate will be affected by the number of spatial streams. The number of bits each subcarrier can transmit is the number of coded bits per subcarrier. The higher the coding rate, the better. How many ...

First of all, let’s learn about IEEE 802.11ax. In the WiFi alliance, it is called WiFi 6, also known as a high-efficiency wireless local area network. It is a wireless local area network standard. 11ax supports 2.4GHz and 5GHz bands, and can be backward compatible with commonly used protoco...

802.11n needs to be described separately. At present, the mainstream market uses this protocol for WiFi transmission.  802.11n is a wireless transmission standard protocol. It is an epoch-making technology. Its appearance makes the rate of wireless networks increase greatly. In order to improve t...

There are many concepts and protocols involved in wireless networks. In order to give everyone a better idea, I will explain the classification. 1. According to different network coverage, wireless networks can be divided into:  “WWAN” stands for “wireless wide area network.  &...

1. IEEE802.11b and IEEE802.11g are both used in the 2.4GHz frequency band. Let’s explain these two protocols in a continuous way so that we can understand the standards of different protocols. IEEE 802.11b is a standard for wireless local area networks. Its carrier frequency is 2.4GHz, and...

Learn more about IEEE 802.11a in the WiFi protocol, which is the first 5G band protocol. 1) Protocol interpretation: IEEE 802.11a is a revised standard of 802.11 and its original standard, which was approved in 1999. The core protocol of the 802.11a standard is the same as the original standard, ...
